TNR people are very against relocating ferals. Once they start putting food on your property they won't stop. Neither they nor the cats will ever leave while the food attracts more cats. If you pressure them to stop feeding they'll slash your car tires.
Best deterrent is death. I haven't had one come back after being killed yet. Though I sometimes get surprised when I see a lookalike.
I use a combination of foothold traps, trail cameras, Harbor Freight driveway alerts, and air rifles.
They often use the same routes which you can identify...
